I have a 88 S-10 blazer and have a fuel smell inside the truck. I found out it is in the back near the tank. The tank, pump and lines have been replaced. Any ideas????? Thanks

 

Well damn, I have a fuel smell inside the truck coming from the front, lol. Mine's an '87 S10 Blazer.

I'm not sure what it could be if you've replaced all that stuff. Let me know if you find anything out, it may help me.

 

the evap system would be my guess since that is in the area of the fuel tank and deals with fuel vapor

 

The same thing happened on my 93 silverado 5.7, turns out I had a leak up by the exhaust manifold. Just took it to the dealer and got a new one.
